Exploration of heat and momentum transfer in turbulent mode during the precooling process of fruit.

ABSTRACT: Developing a simulator is a prevalent method for the study of any process in which various phenomena occur simultaneously, such as the precooling process; it is also necessary in package designing. During the precooling process of fruit and in the case of large packages at high airflow rates, the flow regime inside the packages is turbulent, which is in most studies assumed to be a laminar flow that causes low prediction accuracy. In the present study, a mathematical model consisting of heat and momentum transfer in the case of a transient and a k-ɛ turbulence model, respectively, was developed in the precooling process of fruits. Two packages and two airflow rates were used to validate the model. The results demonstrate that the turbulence-model-based simulation of the precooling was carr
